August - we've been using 1/2" emt between arrays with plastic bushings to
protect wires and a dual "minerallac" clamps (

to tie the conduits to the riser on the array support. Has worked well over
the years and the inspectors like the "bond" between the arrays.....

Subject: [RE-wrenches] Rooftop wiring methods between multiple subarrays
Hi Wrenches,
I’m looking for fresh ideas on how to run USE-2 wires
between subarrays on rooftops. Let’s say we have a flat roof commercial
system with dozens of separate rows of modules. How would you folks run the
USE-2 wiring between these arrays? We’ve been using J-boxes and EMT which
is robust but time consuming. I’ve also used strut with a cap strip on
the top which effectively makes a wire raceway but it is difficult to properly
ground both ends of the raceway and is also time consuming.
Looking forward to hearing your ideas. Best, August
